Both the upper barrelv A1 and the lower barrel A2 are provided at either side with separate horizontal projecting-weldingprojections a which are welded vonly at c, preferably by electric point weldhe'welding places c are at a considerable distance from the barrel walls so that the latter lare not exposed toinjurious'heating.

at the sighting bar bridge a1, a? at c1, and at the usual barrel hook f at 6".

According to Figure 4, the two bridge halves a1, a2 are further extended round the circumference of the barrels, so as to torni bottoni bridges a, a* which surround the barrels A', A2. The welding could be ell'ected on butt or overlapping contact aces as indicated at c3 and c4.

vFigure 5 shows in cross-section a bock rifle or gun like Figure 1, with barrelsI A1, Af. The welding` projections a are reduced in cross-section by milled recesses c, e so that the welding places c can be nearer to the barrel wall. j

Figure (5 shows a three barrel gun such as Figure 2; in addition to the separate Vwelding projections a, the sighting bar (1.1, a2 is utilized in this case for welding; its cross-section is reduced by milled recesses e, e.

According to Figures f7 and 8 which correspond to the constructions in Figures l and 2, the welding projections a are formed by slots b into bridges which extend parallel to the barrel walls unlike in Figures 2-4 in which the bridges extend at right angles to the barrel walls. The Welding projections are here insulated from the barrel walls by means of the said air slots b so that the welding places c can be quite close to the barrel walls.

According to Figures 9 and 10, the sighting bar, like in Figure 6, is utilized as a welding projection; the projection places are separated from the barrel Walls by slots b1, b2, moreover milled recesses e e are provided so that the welding can be made quite close to the barrel wall.

Figures 11 and 12 show the position of the welding joints along the stock.

According to Figure l1, the welding is done at the sighting bar al and at the barrel hooks f f at e c.

According to Figure 12, the Welding is done also at the sighting bar al, a?, and on separate bottom welding projections a whilst the barrel hooks f, f engage each other loosely.

Having now particularly described vand ascertained the `nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A fire arm with several barrels, characterized by the projections intended for the connection of the barrels being welded together only at places projecting beyond the barrel Walls in order to protect the latter from injurious heating.
